Email attachments and “anyone with the link” shares are how client files leave your control. Secure sharing means the right people, for the right time, with an audit trail—especially for legal, medical, and financial documents common in Orange County professional services.
Convenience that skips permissions is a future incident report.
Prefer these patterns
SharePoint or OneDrive with specific people, not anonymous links, for sensitive work.
Expiration dates on external links.
Named group permissions instead of one-off anonymous URLs.
Version history instead of final_v9_REAL.docx in email.
Avoid
Personal Dropbox or Google Drive for company PHI or client PII.
USB drops between job sites without encryption.
Forwarding entire mailboxes “so the contractor can catch up.”
Guest access hygiene is covered in Microsoft 365 guest sharing.
